摘要：A high-speed optical recording apparatus for generating a write signalaccording to an input RLL modulated waveform to control a writing power of a pickup.The high-speed optical recording apparatus contains a rough delay element, which

generates rough delay parameters and fine delay parameters according to a set of writestrategy parameters and delays the EFM waveform generating a first delay signal. Thehigh-speed optical recording apparatus also contains a fine delay chain, which includes aplurality of delay cells in serial connection. Each delay cell delays the first delay signal bya predetermined time period. The fine delay chain delays the first delay signal accordingto the fine delay parameter to generate the write signal.
